| Outline of Final Research Achievements |
Global warming could significantly impact interactions between plant species and their users. To begin understanding how environmental changes influence these interactions, we employed metabarcoding techniques to identify unknown plant users. Additionally, we carried out comparative phylogeographic analyses of several insect species involved in symbiotic relationships with figs to ascertain the effects of past climate changes on these interactions. Our findings suggest that the distribution changes of the fig wasp, which is in an absolute symbiotic relationship with figs, mirrored the distribution changes of figs during the last glacial period and in post glacial era.

近年急速に進行している地球温暖化は，さまざまな様相で地球環境を変化させている．当然のことながら，生物多様性への影響も大きいと考えられる．特定の種の分布は，温暖化に伴い，極方向へ移動していくと考えられるが，その際の移動スピードは生物種によってかなり異なる可能性がある．そうすると，これまで長期間にわたって維持されてきた生物間相互作用にミスマッチが生じる可能性がある．その結果として，生物多様性にますます重大な影響が生じるかもしれない．本研究では，そのような観点から研究を行った．
